Serial peripheral interface (SPI)/Inter-integrated sound
interfaces (I
Up to two SPIs are able to communicate up to 18 Mbits/s in slave and master modes in full-
duplex and simplex communication modes. The 3-bit prescaler gives 8 master mode
frequencies and the frame size is configurable from 4 bits to 16 bits.
One standard I
can operate as master or slave at simplex communication mode. It can be configured to
transfer 16 and 24 or 32 bits with16-bit or 32-bit data resolution and synchronized by a
specific signal. Audio sampling frequency from 8 kHz up to 192 kHz can be set by 8-bit
programmable linear prescaler. When operating in master mode it can output a clock for an
external audio component at 256 times the sampling frequency.
